Overview
Triceratops was one of the last non-avian dinosaurs to exist before the mass extinction event 66 million years ago, instantly recognizable by the massive bony frill extending from the back of its skull and the three prominent horns on its face. It lived across what is now western North America, sharing its environment with predators like Tyrannosaurus rex.
Appearance
It had a large, bulky, four-legged body, a beak-like mouth suited for cropping tough vegetation, and a distinctive skull featuring two long brow horns above the eyes, a shorter horn on the snout, and a wide bony frill extending back over the neck. The frill may have served multiple purposes, from protecting the neck to signaling age or fitness to rivals and potential mates.
Habitat & Distribution
The triceratops is found in grassland, forest habitats.
Diet & Behavior
Diet: Herbivore — Plant-eating animals that graze or browse on grasses, leaves, and other vegetation, from tiny insects to giant elephants.
Triceratops was a herbivore that likely fed on low-growing plants using its sharp beak and rows of grinding cheek teeth adapted for processing tough, fibrous vegetation. Fossil evidence, including healed injuries on frills and horns, suggests Triceratops individuals sometimes engaged in horn-to-horn combat, possibly over territory or mates, similar to how modern horned mammals compete today.
Predators

Prey
This species does not prey on other animals.
Interesting Facts
